View source: R/sesem1.0.2.r

Description

Modification indices averaged across all lag distance bins (the non-spatial bin is not included) are calculated for each potential path addition to the structural model. Option modcut suppresses the printing of modification indices of less than that value.

Usage

1
avg.modindices(spatial_model_results, modcut = 4)

Arguments

spatial_model_results

a list object produced by function runModels

modcut

The minimum averaged modification index to print. Default is 4.
